Ubuntu 21.04 新戴尔 Inspiron 7700 AIO 没有声音

我刚买了一台新的戴尔 Inspiron 7700 AIO 电脑，配备第 11 代 i7 CPU。安装了 Ubuntu 21.04，它基本运行正常。但是，内置扬声器没有声音，声音设置面板显示“虚拟输出”是唯一的输出选择。

我目前已连接了一个蓝牙声音输出设备，并成功使用它进行声音输出，但我更喜欢使用 AIO 的内置扬声器。

关于我可以检查什么，您有什么想法吗？

Ubuntu 21.04

内核 5.11.0-36-通用

解决方法是将以下内容添加到 /etc/modprobe.d/alsa-base.conf 并重新启动...

# Enable internal audio and headphone jack on Dell Inspiron 27 7700 AIO
options snd-hda-intel model=dell-headset-multi
